i need help with this question

1. The temperature of an office building in the winter is allowed to drop to 60 F during off-
hours, and then is ramped back up to 70 F for the working hours. A graph of this
temperature profile T(t) over a 24-hr time cycle is given below. Derive an expression for
T(s). (Note – You can assume the temperature is held at 60 F as time → 00)
